The two GetAxis expressions should be connected by some logical operator (probably OR), and Input.Get doesn’t exist: it probably should be GetButton. Additionally, you should use some clear and self explanatory code layout - at first sight, your code seems to have two else for a single if! Indentation and brackets are your friends: use them wisely, or you may end with a completely unreadable code - a really bad thing when you need to fix logic errors.

// you must have a logical OR connecting the two expressions:
if ((Input.GetAxis("Vertical")!=0 ) || ( Input.GetAxis("Horizontal")!=0) ){
  // Get what? Probably it should be GetButton:
  if (Input.GetButton ("sprint")){
    PlayerState = 2;
  } else {
    PlayerState = 1;
  }
} else {
  PlayerState = 0;
}
